title: Ectopic opening of the vas deferens into a Müllerian duct cyst.
abstract: Two consecutive cases of ectopic opening of the vas deferens into Müllerian duct cysts are presented, with descriptions of the presentation, physical examination, radiographic and ultrasonographic images, surgical findings and treatment undertaken. In both cases, ablation of the cyst and ligature of the vas deferens was the technique employed. Both patients are currently well, with normal urinary flow and no urinary tract infections, 3 years after surgery. Ectopic opening of the vas deferens into Müllerian duct cysts is a rare entity but should always be considered when a child presents with purulent urinary discharge and abdominal tumor. Surgery is the only treatment recommended.
